RockShox’s Charger damper features a sealed rubber bladder that expands when the fork is compressed, so oil and air stay separate, virtually eliminating any chance of foaming or bubbles in the system. What does this mean? It means the fork rides higher in the travel, in the plushest part of the stroke, preserves the bike's geometry, and recovers from hits quickly, all while maintaining incredibly consistent damping, no matter how long the downhill.
